Abstract

835,720. Welding by fusion. MUREX WELDING PROCESSES Ltd. April 28, 1958 [May 10, 1957], No. 14927/57. Class 83 (4). To facilitate starting of a welding arc, a conductive pellet in the form of an agglomerated mass of powdered metal or cadmium oxide having a resistance of 0.1... 100 ohms is interposed between the electrode and the work. The pellet is porous or the powder is bonded with a binder, e.g. a silicate, which liquefies or volatilizes under action of the arc to make the pellet porous. The pellet may be magnetized or coated with an adhesive to adhere to the electrode. It may be in the form of a disc or a cylinder 11, Fig. 2, fitting on the electrode 13 or be shaped as shown in Fig. 3 to fit into the welding seam. It can be used to start the arc in flux submerged arc welding. Constituents may be metals such as iron, nickel, aluminium and copper and are stabilizers such as calcium silicide.
